Letters Patent No. 92,135, dated .Tune 29, 1869. Y

IMPROVEMENT IN SULKY-CULTIVATOR.

The Schedule referred' to in these Letters Patent and making part of tho name.

.To whom 'it may concern e Be it'known that I, NATHANIEL WILSON, of St.

y Louis, in the county of Gratiot, and State of Michigan, have invented a new and useful Improvement in Sulky-Cultivators; andv I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and being a part of thisI specification.

Figure 1 is a side elevation of my invention. Figure 2 is a plan view fromthe top. Like letters indicate like parts in each figure. The nature of this invention relates to an improvement in wheel, or sulky-cultivators; and consists in` so constructing the same, that when employed in cultivating rows of corn, and straddling the same, should the rows be crooked, the bars upon each side, which carry a part of the teeth, may be moved laterally to or from the row, by the foot of the driver pressing upon suitable treadle-levers.

It also consists in attaching tothe axle forwardprojecting arms, to which the cultivator-ti'ame is `pivoted, and in a peculiar arrangement for raising and lowering said frame, for the purpose of cultivating at any desired depth.

In the drawings- A A is a frame, composed of three longitudinal bars, a, and two cross-ties, b, suitably put together by propel' mortises and tenons.

B are two other longitudinal bars, pivoted at the rear end of the frame, by means of metallic plate, c, and bolts, d.

At the front ends of these bars B, there are secured other similar metallic plates, e, which over and underlap the front cross-tie ofthe frame.

1 Bolts, f, provided with suitable nuts or keys, pass through the ends of t-he plates e and the front crosstie, to hold said bars B rigidly in place when desired;

or said bolts may be removed when required, for the purposes hereinafterdescribed.

To the longitudinal bars a and B are properly secured two series ot' standards, C, and steel or iron cultivatorteeth, g, in such a manner that the rear series follow the spaces left between the front series, andthe two outside ones of the rear engage with the soil immediately outside of the outside ones of the front series.

This frame A is securely pivoted to the front ends of the projecting arms D, the rear ends of which are rigidly secured to the axle E, upon which the tractionwheels F revolve.

axle, are fastened, at their opposite ends, to the rear end of the frame A. Y

A lever, H, is secured to one. end of this rock-shaft, which, by its engagement with the notched quadrant I, secured to the topof one of the projectingl arms D, holds the frame in position when raised by means of the arms h, chains, and pulleys, already described.

When it is desired to drop the frame, to allow the cultivator-teeth to enter the ground, the lever should be disengaged from the notched quadraut,when the weight ot' the rear end of the frame will cause it to drop. The position of the frame, standards, and cul tivator-teeth,'when dropped, is shown in red lines in I tig. 1'.

J are 'treadles, the front ends of whigh are pivoted, one each side of the centre-bar a, by a suitable bolt, which also secures the pole K to the-implement.

The rear ends of these treadles are extended to a proper position to be operated by the foot of' the driver, upon the seat L.

'lo each one of these treadles is secured a rope or chain, m., which ropes pass in opposite directions ovel the pulley n, which is secured to the centre-bar a, and the outer end of each ot' these chains are secured to the longitudinal and pivoted bars B. f I V By means of these treadles and chains, the. operator can at will, alternately pressing the treadles,

change the position and direction of the cultivatorteeth, which aresecured to said bars B. This change is shownin red lines in fw. 2.

It will be borne in mind, that when it isdesired to change the direction, as just described, the bolts f must he removed and they may be replaced at any f time that, it is desired to use the implelnent\vith the bars B rigidly in a parallel position with the bars a.

Suitable iron braces,'0, secured near the front end of the frame, and extending downward and rearward to the standards 0,-keep them in their relative position to the frame.

WVhat I claim as my invention, and desire to secure by Letters Patent,.is-

1. The' brs B, secured to the frame A, as described, and operated by the treadles J, ropes or chains m, and pulley n, substantially as set forth. 2. The rock-shaft G, arms h, ropes or chains i, pulleys K, lever H, and quadrant I, in combination with thelongitdinal bars a and B, provided with stand-l ards 0, and cultivator-teeth g, operating 'as and for the purposes described.

3. The arrangement of the parts A, B, C, D, E, F, G, H, I, J, K, L, a, b, c, d, e,.f, g, h; t, k, m, n, and o, or

` ,their equivalents, when combined and operating sub-,f

stantially asand for the purposes herein set forth.

NATHANIEL WILSON.
